The standard normalized step-size LMS algorithm computes the current step-size according to $$ \mu = \frac{c}{s_k^T \cdot s_k} $$ where $c$ is a suitable scale factor and $s_k^T \cdot s_k$ is the total energy of the current tap inputs. The algorithm aims to adjust step size according to input signal power; when input has large power then decrease the step-...

I can add that LMS algorithm has a sample-based update.
